BAND-CUTTER roe museums MACHINE...

To ALL WHOM IrM-AY oononnn;

Be it known that I, WILLiAM P. FBENOg, of Washington, in the State of Iowa, haveinvented a certain new and useful Improvement on Band-Gutters for Threshing Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the some, reference being bad to the accompanying drawings and to the letters hnd mzirks thereon, which said drawings form part of this specificatiop, and show my invention applied to the feeding-trough of a threshing machine Figure lbeing a. side view of the trough, and

Figure 2 a. top view thereof. A

In both of these figures where like parts are shown like letters and marks are used to indicate the parts.

An, upper rotary cutter, a, is attached to a. shaft, b, having its bearings in arms 0 pivoted to the sides of the trough d, end the arms b secured to each other by a cross-bar, e. A slot,f, .in the arms 0 gives passage to the pivoting screw or pin, and allows the arms to be moved forward or backward, so that the cutter and its shaft may be adjusted both forward and backwardund upward and downward, the better to adapt the cutter to the difference in size of sheaf, and for, any other purpose for which adjustment may be required. The cutter (I is rotated by at hand, 9, passing mound a pulley, h, on the shaft 6, and around the pulley 130i the feeding-rollers A lower rotary cutter, is, is afixed to a shaft under the bottom I of the trough, a slot, m, therein giving it a way or passage. The shaft of this cutter has its bee-rings in the arms of another shuft pivoted at n into blocks,

which, by the screw and nut a, are held on the inner side of the slot m, against and along: which the block hnd screw may traverse, so that the cutter k and its shaft may be moved backward and forward An arm, 12, extends downwards from the pivoted shaft to the toothed spring Jar q. The moving forward of the lower end of the arm 1) elevates the cutter]: through the slot m, while the moving of the only backward depresses the cutter k, s slot, 1', in the side of the trough, allowing of this movement of thecutter and shaft. This cutter may be brought below the bottom 'of the trough when only the upper cutter can be used. The lower'eutter is has, therefore, also the adjustment upwards and downwards and backwards and forwards. The movements of this cutter upwards may be effected by an eccentric or com instead of the means shown. The cutter k derivosiits motion,

its rotation, by a. band around a pulley, 8 oh the end of its shaft, and around the pulley z'fof the feed-roller,

The cutters or knives a and k maybe formed as shown by thedrawings, orthey maybe of the form of segments .projecting from a periphery, or of any pointed form desirable- What I claim as my improvement on the rotary band-cutter, is

The double adjustability caused by the means substantially herein'set forth.
